Live-Streaming Coin Video App

I’m building a mobile video application inspired by So Live and need it released on both iOS and Android. The heart of the product is real-time live streaming where viewers can interact with hosts, create and update their own profiles, and spend or earn virtual coins.

Coins must work in two ways: users can buy pre-defined bundles through in-app purchases or accumulate them through in-app activities and rewards. Package sizes and pricing tiers will differ from the reference app, so the bundles and their validity periods need to be completely configurable from an admin view or a simple JSON file you set up.

Key elements to deliver
• Native or cross-platform code that compiles cleanly for App Store and Google Play.
• Low-latency live video streaming with chat and basic moderation tools.
• Secure in-app purchase flow for iOS & Android, storing transactions on the backend.
• User profile module (avatar, bio, coin balance, past streams).
• Coin wallet logic covering earn, spend, and real-time balance updates.
• Lightweight admin or config file to manage coin bundles, prices, and validity length.
• Complete source code, API docs, and a test build for each platform.

Send over a concise proposal highlighting the tech stack you prefer (e.g., Flutter with Firebase, React Native + Node, or fully native Swift/Kotlin), a realistic timeline, and a fixed price broken into milestones. I’ll award the project to the best combination of approach, experience, and quote.
